what do you need, the sine and cosine questions?

OpenStudy (anonymous):

i just dont understand what im supposed to do on the last 2 pages.

OpenStudy (anonymous):

what you need is a good trig cheat sheet look at the unit circle on the last page of the attached

OpenStudy (anonymous):

lets say you want \[\cos(\frac{\pi}{6})\] find the angle \(\frac{\pi}{6}\) and look at the corresponding point on the unit circle the first coordinate of that point is \(\cos(\frac{\pi}{6})\) and the second coordinate is \(\sin(\frac{\pi}{6})\)

OpenStudy (anonymous):

hmmm

OpenStudy (anonymous):

let me know when you see it, then we can do one more

OpenStudy (anonymous):

i see it, whats confusing me is that, im not sure what my teacher is wanting me to put in the blanks on the last 2 pages.

OpenStudy (anonymous):

i think the values of sine and cosine asked for

OpenStudy (anonymous):

as for the first question, since the radius is 1, instead of \[\cos(\theta)=\frac{opposite}{adjacent}\] it is just \[\cos(\theta)\] is the first coordinate of the point on the unit circle (since the hypotenuse is 1)

OpenStudy (anonymous):

i still dont understand. sorry
